Application :tiled November 4, 19.16. Serial No. 129,437.

My inventionA relates to the construction' of car couplers of the Master Car Builders type and particularly to the locking mechanism thereof. rlhe primary object of the invention is to provide means whereby the locking mechanismk ofa coupler may be interchangeably assembled with different wellknown forms of lock actuating devices, thusV rendering it unnecessary to provide a different formV of lock for assembly with each type of lock actuating mechanism, and thereby reducing the number of repairV parts required tobe carried in stock by the railroad company. A further object of the invention is to provide a simple, strong and efficient form of knuckle lock for Vuse in a car coupler having lockeset and knuckle opening devices.

In the drawings illustrating the preferred embodiment of my invention, the scope whereof is pointed out in the claims,

Figure 1 is a side elevation of a coupler mechanism embodying my invention, thev lock actuating device being of the type inf volving a pivoted lifter member arranged and operating in a vertical plane extending longitudinally of the coupler.

Fig. 2 is a front elevation of a coupler mechanism embodying my invention, the lock actuating device being 0f the type involving a pivoted lever operating in a vertical plane extending transversely of the coupler head, and the interior mechanism of the coupler being shown in dotted'lines.

Fig. 3 is a detail side elevation of the cou# pler lock looking from the knuckleside of the coupler head.

Fig. 4 is a detail front view of the coupler lock, showing the lockset member assembled therewith.

Fig. 5 is a sectional view taken on the line 5 5, Fig. 4, looking toward the lower end of the lock.

Fig. 6 is a section on the line 6 6, Fig. 4, looking downwardly; and.

Fig. 7 is a plan view of the upper end of the lock, showing thelock-set member assembled therewith.

' 'In the drawings, 1 is the coupler head and 2 is the knuckle pivotally mounted thereon, Thel lock 3 coperates with the tail 4 of the knuckle in the usual manner to retain the knuckle 2in coupled position, as indicated v in dotted lines in Fig. 2.1

In the construction shown in Fig. 1 the lock 3 is adapted to be lifted by means of a vertically swinging actuating arm or lever 5 that extends longitudinally of the coupler,

said lever being provided at its rear end with oppositely projecting trunnions 6 by which it is pivotally mounted in a bracket 7 secured to the coupler. In the construction shown in Fig. 2 the, mechanism for actuating the lock 3v involves a bell-crank lever 8 that operates'in a vertical plane transversely Vof the coupler head, such head being provided with `'pivot -lugs 9 adapted to receive' a pivot pin 10 by which the lock actuating lever 8 is connected toV they coupler'head.V

Both'of these types of lock actuating mecha; nismrare in use and well known to those skilled in the art. l

The' lock 3, which projects downwardly below the coupler head, is provided near its lower end with a plurality of openings 11 and 12, respectively, which extend at right angles to each other. The opening 11, which is adapted to receive the forward end of the longitudinally extending actuating member 5, preferably extends below vthe opening 12 .that receives the bell-crank lifting lever 8, and,l as shown, the said openings 11 and 12 preferably overlap and communicate with each other as such a construction reducesthe extent to which the lock 3 is required to project below the coupler head.

The lock engaging end of the actuating member 5 is preferably formed with a lock- 'ing shoulder 13, and the lock 3 is formed atv the base ofthe opening'll therein with a corresponding locking face 14, the locking faces 13 and 14 being adapted to bind upon each other when the lock 3 accidentally attempts to Aexecute an unlocking movement, thereby preventing accidental unlocking of the coupler. When the pivoted actuating member 5 is swung upwardly by the rod 15,

the locking faces 13 and 14 are first released Vin and causes said lock to perform an eX- tended unlocking movement. The lock engaging end of the' bell-crank actuating lever 8 is similarly formed with a locking face or shoulder 18 which is adapted to contact and` bind upon a correspondingshoulder 19 of y the lock to prevent accidental unlocking of the'latter, as will be seen upon reference to Fig. 2 of the drawings.

- Near its upper end and on the side toward the knuckle 2 the lock 3 is provided with a lug or projection 2O that is adapted to engage and operate one arm'of a bell-crank knuckle opener 21 that is pivotally mounted within the coupler head in a well known manner. Adjacentto the projection 2O the lock is formed with a slot 22 which receives a lock-set member 23 that is pivotally mounted on said lock by means of a `pivot pin 24 which passes through appropriate Openings 25 and 26 in the lock. When the lock 3 is in locked position the lock-set member 23 rests in a horizontal position on the upper surface of the tail 4 of the knuckle7 but when the lock is raised to unlocked position preliminary to separating the cars the look-set member 23 gravitates to a vertical position and Y its lower end rests upon the upper surface of the knuckle tail, thus maintaining the lock in an elevated or unlocked position.

l claim: K

1. A coupler lock having a plurality of Y intersecting` openings extending at an angle to each other, each of said openings being adapted to receive means for moving said lock to unlocked position.

V2. A coupler lock having a portion adapt# ed to project downwardly outside the headV of a coupler, said projectingv portion being 'provided withy two openings, one of said openings extending longitudinally of the coupler and the other of said openings eX- tending transversely ofsaid coupler,and each of said openings being adapted to receive means for Vmoving said lock to unlocked position. Y f

3. A coupler lock having a plurality of overlapping openings extending atan angle and a lock for said knuckle, said lock beingV provided with means whereby it may interlockingly engage means for actuating said lock, to thereby prevent said lock from accidentally moving to unlockedV position, and being adapted to be operatively assembled with lock actuating means in aplurality Vof relations.

In testimony whereof l alix my signature.
